Clinical Efficacy of 125I Brachytherapy Combined With Anlotinib in Radioiodine Refractory Thyroid Carcinoma Patients

April 14, 2024 updated by: Jiangxi Provincial Cancer Hospital

Clinical Efficacy and Safety Analysis of 125I Brachytherapy Combined With Anlotinib in Radioiodine Refractory Thyroid Carcinoma Patients

A retrospective analysis was conducted on patients with radioiodine-refractory thyroid carcinoma (RRTC) who underwent radioactive 125I seed implantation combined with anlotinib from January 2019 to October 2024 at Jiangxi Cancer Hospital. Data on tumor size changes before and after treatment, serological tests (including serum TG, TgAb, CTn, CEA, etc.), changes in patients' pain scores, and side effects were collected to evaluate the clinical efficacy and safety of this therapy.

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

A retrospective analysis was conducted on RRTC patients who underwent radioactive 125I seed implantation combined with anlotinib from 2019 to 2024 at Jiangxi Cancer Hospital, including 2 cases of papillary thyroid carcinoma (PTC), 4 cases of follicular thyroid carcinoma (FTC), and 2 cases of medullary thyroid carcinoma (MTC).

Prior to the treatment, patients were informed about their condition, the expected efficacy, and the potential side effects and toxic effects of 125I seed implantation therapy combined with anlotinib. All patients accepted the treatment plan and signed an informed consent form. The preoperative evaluation process includes assessments of coagulation function, liver and kidney function, cardiopulmonary function, and local CT scans.

A collaborative effort between physicians and physicists was undertaken to establish a treatment regimen with a prescription dose ranging from 80 to 120 Gy. The CT-guided 125I seed implantation procedure was conducted according to the prescribed treatment regimen. On the day of completion of the 125I seed implantation procedure, all patients began treatment with anlotinib. Patients undergo 14 consecutive days of treatment followed by 7 days off, constituting one cycle. This cycle is repeated until progressive disease (PD) occurs or the patient shows intolerance to the treatment.

Subsequent evaluations were scheduled post-surgery, focusing on lesion dimensions, serum Tg levels, pain levels, and adverse reactions. Lesion size was determined using CT imaging. Each measurable lesion underwent an average measurement derived from a minimum of three readings, with all measurements conducted by the same individual to minimize measurement discrepancies.

Response Evaluation Criteria in Solid Tumors (RECIST 1.1) [1] were used to assess treatment response. Use the Visual Analogue Scale to record patients' pain scores. Adverse reactions, including infection, bleeding, pneumothorax, bone marrow suppression, and seed displacement, were recorded. Adverse events were graded according to the Common Terminology Criteria for Adverse Events (CTCAE) version 5.0.The data were analyzed using IBM SPSS 27.0.

Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
The CT images were used to measure the change in the maximum diameter of the lesion in millimeters.
Time Frame: Patients were evaluated preoperatively and at 2, 4, and 6 months postoperatively.
Lymph nodes were assessed based on their shortest diameter, while other target lesions were evaluated based on their longest diameter. Each measurable lesion underwent an average measurement derived from a minimum of three readings, with all measurements conducted by the same individual to minimize measurement discrepancies. Response Evaluation Criteria in Solid Tumors (RECIST 1.1) were used to assess treatment response[1].
Patients were evaluated preoperatively and at 2, 4, and 6 months postoperatively.
Serological assessment
Time Frame: Patients were evaluated preoperatively and at 2, 4, and 6 months postoperatively.
Including serum Thyroglobulin (Tg) and serum Anti-thyroglobulin Antibody levels (TgAb) in thyrotropin-inhibited states, as well as tumor markers such as Carcinoembryonic Antigen (CEA).
Patients were evaluated preoperatively and at 2, 4, and 6 months postoperatively.
Use the Numerical Rating Scale (NRS) to record patients' pain scores.
Time Frame: Patients were evaluated preoperatively and at 2, 4, and 6 months postoperatively.
The scale ranges from 0 to 10 points, with pain increasing incrementally. 0 indicates no pain, 1-3 indicate mild pain that is still tolerable and does not interfere with sleep or normal life, 4-6 indicate moderate pain that interferes with sleep and requires analgesic medication to alleviate it, and 7-10 show intense and intolerable pain that seriously interferes with sleep and diet and requires strong analgesic drugs.
Patients were evaluated preoperatively and at 2, 4, and 6 months postoperatively.
Number of participants with treatment-related adverse events as assessed by Common Terminology Criteria for Adverse Events (CTCAE) version 5.0
Time Frame: Assess within six months after surgery.
Adverse reactions, such as pain, pneumothorax, hemorrhage, myelosuppression, infection, radiation inflammation, necrosis, hand-foot syndrome, hypertension, proteinuria, and diarrhea, were observed and recorded. The severity of the adverse reactions was graded according to the CTCAE v5.0, with grades ranging from 1 to 5, where grade 1 represents the mildest and grade 5 the most severe.
Assess within six months after surgery.
